Abstract

An extraction cleaner includes a portable extractor and a base adapted to be moved to perform a cleaning operation on a floor surface when the portable extractor is operably mounted to the base. The portable extractor includes a recovery tank assembly provided on the housing adjacent to the recovery tank assembly.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. An extraction cleaner, comprising:
 a housing; 
 a recovery system, comprising:
 a recovery tank assembly provided with the housing, the recovery tank assembly comprising a recovery tank having an open top at least partially covered by a cover assembly; 
 a suction inlet in fluid communication with the recovery tank assembly via a working air path; 
 a suction source; and 
 a recovery duct assembly interconnected with the recovery tank assembly, the recovery duct assembly comprising at least one vertical duct adjacent a rear face of the recovery tank; wherein the at least one vertical duct of the recovery duct assembly comprises a vertical inlet conduit and a vertical exhaust duct. 
 
 
     
     
       2. The extraction cleaner of  claim 1 , wherein the rear face of the recovery tank comprises a recessed portion and the vertical inlet conduit and the vertical exhaust duct are received therein. 
     
     
       3. The extraction cleaner of  claim 1 , wherein the recovery tank is removable from the housing. 
     
     
       4. The extraction cleaner of  claim 3 , wherein the vertical inlet conduit and the vertical exhaust duct remain with the housing when the recovery tank is removed from the housing. 
     
     
       5. The extraction cleaner of  claim 1 , wherein the vertical inlet conduit and the vertical exhaust duct are provided in a side-by-side orientation. 
     
     
       6. The extraction cleaner of  claim 1 , wherein the cover assembly further comprises a separator having a recovery tank inlet in fluid communication with the vertical inlet conduit and a recovery tank exhaust outlet in fluid communication with the vertical exhaust duct. 
     
     
       7. The extraction cleaner of  claim 1 , further comprising a float provided with the recovery tank assembly. 
     
     
       8. The extraction cleaner of  claim 7 , wherein the float is removable with the cover assembly. 
     
     
       9. The extraction cleaner of  claim 1 , wherein the recovery system further comprises a separator adapted to provide fluid separation between an inlet of the recovery tank assembly and an exhaust outlet of the recovery tank assembly. 
     
     
       10. The extraction cleaner of  claim 1 , wherein the recovery duct assembly is located between the recovery tank and the suction source when the recovery tank is mounted to the housing. 
     
     
       11. The extraction cleaner of  claim 1 , wherein the housing comprises a lower body in which the recovery tank is removably received. 
     
     
       12. The extraction cleaner of  claim 11 , wherein the lower body encircles the recovery tank. 
     
     
       13. The extraction cleaner of  claim 1 , wherein the suction source comprises a motor and blower assembly. 
     
     
       14. The extraction cleaner of  claim 1 , further comprising a fluid delivery system for dispensing a cleaning fluid and comprising a supply tank assembly provided on the housing adjacent to the recovery tank assembly. 
     
     
       15. The extraction cleaner of  claim 1 , further comprising an accessory hose and the suction inlet is an inlet of the accessory hose. 
     
     
       16. The extraction cleaner of  claim 1 , wherein the extraction cleaner is a portable extractor. 
     
     
       17. The extraction cleaner of  claim 16 , further comprising a base including a suction nozzle and wherein the portable extractor is adapted to be operably mounted to the base. 
     
     
       18. The extraction cleaner of  claim 17 , further comprising a diverter valve for selectively fluidly interconnecting the recovery tank with one of the suction inlet and the suction nozzle, the diverter valve, comprising:
 a follower provided on one of the portable extractor and the base; and 
 a cam provided on the other of the portable extractor and the base; and 
 wherein the diverter valve opens fluid communication between the recovery tank and the suction nozzle when the portable extractor is operably mounted to the base. 
 
     
     
       19. The extraction cleaner of  claim 17 , wherein the base comprises a base platform that supports the portable extractor at a forward portion.
